I was about to make a new thread because of this issue. I notice my ssd was low on space with a window message.. had 20gb free and than it was down to 500kbs... And found out meta tester is causing it. So i re install it on my other normal hdd in the system which had 50gbs free and about 20min in its down to 12gbs.. So yea its a issue on the software side and not your hard drive. My ssd and hdds is in good shape and fresh install of windows also.
When will the next build be release?
I also with same problem. Metatrader version 5 with build 2025.
The out of space causing some agents to become disabled.
I could see that temporary files with prefix name bar were created.
